OK, I know this sounds ridiculous, but in a nutshell. Last year, dd was close to a girl in her class (X), and I became friendly with her mum. Unfortunately, the school mixed up the classes and they were split up for this year and now they see one another only during playtimes and breaks and according to dd are still friendly but just don't see one another much. Dd's best friend(B)(who she has known since babies), is in dd's class and they spend a lot of time (if not most) of their time together both in and out of school. Anyway, dd's birthday is in 3 weeks' time and I sent out invites (10 kids only) and deliberately we chose to invite X because dd still likes her and feels they are still friends. Anyway, has not responded to the invite despite me texting her mum (who used to respond to every text asap)0. I mentioned this to B's mum who is also my best friend. She then said in horror "isn't your dd going to X's party then??".....turns out that X is having a party and has invited my B (who she hardly knows) but hasn't invited my dd. There seem to be quite a lot of people going and I just can't understand why she wasn't invited. Dd says they haven't fallen out or even had bad words and confirms that X really doesn't know D that well. I'm at a loss. I did leave a message on X's mum's phone just asking her if she'd received the invite and if she could make it but still, no response. I'm wondering whether she's embarrassed or if there's a bigger issue here. What would you do? I really it's JUST a party but I feel so bad for dd - she feels really embarrassed and is upset but trying not to show it. I even asked her if perhaps she had lost her invite but she said that apparently they were handed out at school when she wasn't around. Why would she deliberately invite B knowing that she would tell my dd and risk her being upset like this? I'm half cross and half sad.
